- I've problems installing an HP 4mm DAT on a SparcStation 1+.
- DAT data have been included in the kernel as needed
- Here follows a part of the messages at boot time: the scsi Target 3
- (disk sd0) has been included because it's referenced later, the DAT
- is scsi Target 5 as shown below.
-
- --------------------
- Jan 21 12:26:07 euterpe vmunix: esp0: Target 3 now Synchronous at 4.167 mb/s max transmit rate
- Jan 21 12:26:07 euterpe vmunix: sd0 at esp0 target 3 lun 0
- Jan 21 12:26:07 euterpe vmunix: sd0: <p cyl 1626 alt 2 hd 15 sec 53>
- ......
- Jan 21 12:26:07 euterpe vmunix: esp0: Target 5 now Synchronous at 5.0 mb/s max transmit rate
- Jan 21 12:26:07 euterpe vmunix: st1 at esp0 target 5 lun 0
- Jan 21 12:26:07 euterpe vmunix: st1: <HP-354XXA 4mm DAT>
- --------------------
-
- The scsi chain also includes a QIC-150 tape as st0 not shown above.
- First strange behaviour: Target 5 is "Synchronous", something I expected
- from disks and not from tapes (the QIC-150 is not declared as Synchronous).
-
- At bootstrap time the DAT was switched off.
-
- Now exactly when I switch on the DAT I get the following
- messages on the console:
-
- ---------------------
- Jan 22 08:54:26 euterpe vmunix: esp0: unexpected SCSI bus reset
- Jan 22 08:54:26 euterpe vmunix: esp0: Target 3 now Synchronous at 4.167 mb/s max transmit rate
- Jan 22 08:54:27 euterpe vmunix: esp0: unexpected SCSI bus reset
- Jan 22 08:54:27 euterpe vmunix: esp0: Target 3 now Synchronous at 4.167 mb/s max transmit rate
- Jan 22 08:54:27 euterpe vmunix: esp0: unexpected SCSI bus reset
- Jan 22 08:54:27 euterpe vmunix: esp0: Target 3 now Synchronous at 4.167 mb/s max transmit rate
- Jan 22 08:54:27 euterpe vmunix: esp0: unexpected SCSI bus reset
- Jan 22 08:54:27 euterpe vmunix: esp0: Target 3 now Synchronous at 4.167 mb/s max transmit rate
- Jan 22 08:54:30 euterpe vmunix: esp0: unexpected SCSI bus reset
- Jan 22 08:54:30 euterpe vmunix: esp0: Target 3 now Synchronous at 4.167 mb/s max transmit rate
- ---------------------
-
- And whenever I try to do something on the DAT tape, I get the following:
-
- ---------------------
- mt -f /dev/rst1 status
- /dev/rst1: no tape loaded or drive offline
- ---------------------
-
- Note: the tape *IS* loaded and drive lamps show "online" :->
-
- I'd appreciate very much if somebody can help me.
